As you know, this weekend several divers went missing during a dive in the Red Sea. Apparently, five divers -- three Russians, a Dutchman, and an Egyptian guide -- were exploring a reef off Marsa Alam when the instructor warned them of sharks and instructed the group to surface. Several hours later, one of the Russian divers stumbled onto shore and told authorities about the accident. The other four never appeared.

A helicopter and 15 boats have been searching the area for four days, but today, officials called off the search. According to Alaa El Din Abdelgeleel of the Red Sea Association for Diving and Marine Sport, "I am sorry to say there is no chance to find them alive. We are limiting the search to the coastal areas, looking for their bodies."

Egyptian authorities are not planning to charge the owner and employees of the dive center that organized the excursion. An inspection concluded that the dive center had all necessary licenses, and that its equipment was in good condition. Rather, the prosecutor concluded, "Bad weather conditions, large waves, and the fact that the current swept the tourists away from the vessel were the main causes of the accident."
